4.1 USING LANVIEW
The 2E253-49R uses Cabletron Systems’ built-in visual diagnostic and status monitoring system
called LANVIEW. The LANVIEW LEDs (Figure 4-1) allow quick observation of the network
status to aid in diagnosing network problems.
Viewing Receive and Transmit Activity
Only one group of segments may be viewed at a time.
To view the receive and transmit activity on a group of segments, press the GROUP SELECT
button (see Figure 4-1) to step to the group of interest (Group 1 through 4). Each time the GROUP
SELECT button is pressed, the next GROUP LED (1, 2, 3, or 4) lights, indicating which Group is
selected. The receive and transmit activity for that group of segments is then indicated by the RX
and TX LEDs for each segment.
